Mark Sanford Pictures Reportedly Show Him With Mistress While Serving As Governor

A third round of pictures of former South Carolina Governor Mark Sanford and his mistress, María Belén Chapur, are hitting the web Monday, this time supposedly depicting the two during Sanford's tenure as the state's chief executive.

Radar Online, which has released the photos, reports that the shots, which show Chapur in a thong bikini, were snapped during a jaunt to the Bahamas during the summer of 2010.

Last week, Sanford and his mistress-turned-girlfriend surfaced in a few sets of pictures, first in an Argentinian magazine showing the two holding hands and later, getting intimate on a beach.

According to the Associated Press:

The Argentine celebrity magazine "Caras," or Faces, published an eight-page spread on Sanford's romantic encounter last week with Maria Belen Chapur, at Punta del Este, Uruguay, a gathering spot for the rich and famous, celebrities and wanna-bes.
